There are some technical pitfalls of USB-C too. Solvable but still present.

Probably the biggest thing people don't think about is how rare USB-C hubs are. I don't mean the ones that adapt to other ports (if you thought of that first, it illustrates my point), I mean one that takes one USB-C and gives you more. For years after 2016, the chip to make this simply didn't exist. Even now, it's expensive. For this reason, it actually makes sense to use USB-A accessories even if your PCs take -C, cause you can always get more -A ports for cheap. So companies still make -A accessories, and even a lot of -C ones tend to come with an A-to-C cable in the box (and no -C to -C cable!).

Non-tech people tend to understand these things without knowing it. They see new port, they say no.
